Patent EP-0435549-A2 (EP)
Inventor: SCHMIDLIN FRED W
IPC: B41J2/415
Filed: 1990-12-18
Abstract: Direct electrostatic printing apparatus including structure for delivering developer or toner particles to a printhead forming an integral part of the printing device. The toner particles are attracted from a toner delivery system (24) towards a support for an image receiving substrate (30), passing through apertures (76) in the printhead structure. The printhead structure includes control electrodes (70) and a shield electrode structure (72) secured to opposite sides of an insulative base (31). The radius of the opening of a control electrode (70) is smaller than the radius of a corresponding shield electrode (72) opening resulting in larger peak potentials for controlling toner flow for the same voltage applied to the control electrode of a printhead aperture wherein the control electrode opening is larger than the opening in a corresponding shield electrode opening.

Abstract: A speech system recognizes words from a spoken phrase that conform to checksum constraints. Grammar rules (30) are applied to hypothesize words (24) according to the checksum constraints. The checksum associated with the phrase is thus inherent in the grammar. Sentences which do not meet a predetermined checksum constraint are not valid under the grammar rules and are therefore inherently rejected (34). The checksum constraints result in increased recognition accuracy.

Abstract: A new two-axis accelerometer comprising an electric motor-driven rotating body that is distinct from the rotor motor and liked to latter via a flexure zone. The resulting rotating body/flexure zone combination may be of either of two types. In a first type the rotating mass is a concentrated mass and the flexure zone permits the rotating body to perform a transversal parallel shift. In a second type the rotating body is an inertia rotor and the flexure zone is an extension of the rotor shaft that embodies a flexible portion. In either type the rotating body/flexure zone combination has two degrees of flexing freedom with two different flexure coefficients in two mutually perpendicular directions both normal to the electric motor shaft. The accelerometer further comprises a deflector shaft coaxial with the rotor shaft and extending beyond the rotating body in a direction away from the electric motor, and in association with said deflector shaft electro-optical measuring means and processor means for measuring linear acceleration components in said two mutually perpendicular directions. In one of its aspects the two axis accelerometer in accordance with the invention measures only two perpendicular components of the acceleration of a body to which it is attached. By another aspect the two axis accelerometer according to the invention is a multisensor being at one and the same time a two-axis angular rate gyroscope and a two axis accelerometer. By yet another aspect of the invention there is provided a multisensor inertial measurement unit (MIMU) serving for the simultaneous measurement of three angular velocity and three linear acceleration components.

Abstract: A television receiver includes a single tuner for tuning both television channels and broadcast FM stations. The tuner is operated at a fixed gain setting in FM reception mode. The tuner serves as the first conversion stage of a double conversion FM receiver, wherein the mixer of an FM radio integrated circuit serves as the second coversion stage. The arrangement operates at a specific and non-arbitrary first IF frequency. The FM receiver is also capable of automatically receiving information services such as, in the United States, National Weather Service broadcasts on that one of NWS's seven allocated frequencies which is operating in a listener's area. The receiver provides an on-screen display of the currently tuned FM channel number.

Abstract: A multiprocessor system includes at least one copy-back cache memory (M i ) connected via a system bus to a common memory (CM). The copy-back cache memory includes a specific flag (S) for indicating whether an identical data is shared with other cache memories, a first unit (P1) for intercepting a response of the common memory to an access when it detects the access from another cache memory to a region where the specific flag is OFF, a second unit (P2) for transferring to the other cache memory an entry corresponding to a region indicated by the access address from the other cache memory and turning ON the specific flag, and a third unit (P3) for sending out a write address to the system bus and turning OFF the specific flag where a write into a shared and modified entry is carried out, to thereby invalidate a corresponding entry in the other cache memory based on the write address. As a result, it is possible to reflect an updated data on another cache memory even if data is newly written into a corresponding entry in the self cache memory after the transfer of the entry to another cache memory, and thus contributes to an improvement in the performance of the entire system.

Title: Method for preparing transformed plant
Inventor: KANEKO TAKAFUMI
IPC: C12N15/09
Filed: 1991-10-31
Abstract: A transformed plant of  Gramineae  is prepared by culturing an anther of  Gramineae  in a callus induction medium and, at a stage immediately before the microspore begins to divide or during the initial division, transducing a genetic substance into the microspore cell through a pore formed by a laser pulse thereby to express genetic information of the genetic substance. 
     According to the present invention, it is unnecessary to prepare protoplasts and therefore, time and operations for transformation can be greatly reduced. Since haploid cells are transformed, the character transduced is conveyed without separating at a later generation. In addition, difficulties in experiments between species and strains are minimized so that it is easy to apply the present invention to practical species. According to the present invention, large pores can be formed as compared to the electroporation method so that DNA or substances having a large molecular weight can be introduced.

Abstract: A system and method whereby a central processor can continue operation beyond a serialization point before the architecture defines that it is permissible to do so. According to the system and method, it is ascertained whether correct results are being achieved after the serializing point. If some doubt develops about the correctness of the results, the processor is returned to its status at the serialization point and the processing is repeated. In one embodiment, correctness of results is determined by way of a monitoring mechanism which depends on the fact that the interactions between CPUs are confined to references to storage. The operations which are performed prior to the time that the architecture allows them, are restricted to ones which depend on fetches made from storage. The needed assurance of correct operation is gained by monitoring the storage locations from which fetches are made on behalf of instructions which logically follow the serializing operation, but which are made prior to the time that fetching is allowed to resume. If those storage locations are not changed during the time between when the first such fetch is actually made from one of them, and the time that fetching is allowed to resume, then the results of the processing which was done by the CPU (based on those fetches) must be exactly the same as if all of the fetches and all of the processing was done in a single instant at the moment that the fetches became allowed.

Abstract: A digital multimeter having automatic function selection capability includes a signal type detector and an analog-to-digital converter formed as an application specific integrated circuit. The signal type detector has a comparator circuit that compares the analog input signal to be measured with predetermined thresholds and stores the resulting values, which are related to the type of analog input signal, in a memory that is also a part of the signal type detector. A controller executes an automatic function selection program that causes the controller to read the stored values and generate a corresponding function code, which causes an analog-to-digital converter to be configured to perform an appropriate conversion function on the analog input signal. When a change in the type of analog input signal is sensed, the controller aborts the present measurement cycle and proceeds with a next measurement cycle in which the changed analog input signal is measured. The controller also produces a change alert signal to indicate that a change in signal type has occurred.
